How accurate is the CAD exchange? When sequential surfaces and non-sequential objects are exported to CAD programs, OpticStudio describes them as NURBS (Non-Uniform Rational B-Splines). A useful overview is given here . A very useful property of the rational b-spline ...

The Stock Lens Matching tool will swap out the lenses in a design for the nearest equivalents in the selected vendors’ catalogs, and offers the potential to make great cost savings in the finished design by eliminating the need for custom manufacture. The tool will give great ...

What is Virtual Propagation? Question: What does it mean to do a virtual propagation of rays? A virtual propagation means the rays are propagated in a direction opposite to the direction energy would actually flow. Virtual propagations are often useful for placing virt...

Introduction In any optical system, light may be scattered at a surface boundary (e.g. due to surface roughness) as well as within the bulk of a volume (e.g. due to light-particle interaction). Both of these scattering phenomena may be modeled in the non-sequential mode o...

Introduction It is sometimes required to represent an optical sub-system without having detailed knowledge of its prescription. For first-order calculations a paraxial lens is adequate, but when wavefront aberrations are needed as well, Zernike phase coefficients can be u...

Introduction Tolerancing is a procedure to evaluate how the performance of a design degrades as a result of manufacturing defects such as element tip and tilts, surface irregularity, glass index errors etc. The traditional design approach is a two-step process. First, ...

Generating a Polarized Light Source All of the polarization analyses in OpticStudio require an input polarization state, usually given as a Jones vector (Jx, Jy) with optional starting phases in X and Y. Input polarization states are entered into OpticStudio in two ways. T...
